STRAW-STACKER. r

SPECIFICATION forming part of Letters Patent No. 430,863,1lated June 24, 1890..

Application filed August 7, 1889.

To all whom, it may concern.-

Be it known that 1, AUGUST LAMMEDEE, of South Bend, in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvements in StraW-Stackers; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this-speck fication, in which- Figure 1 is a side elevation of my improved straw-stacking machine, parts of the carrierbelt-operating mechanism being omitted and broken away, as this invention relates principally to the means for vibrating or oscillat-' ing these carrier-belt frames laterally. Fig. 2 is a plan view of the operating mechanism for intermittently moving the carrier-frames laterally. Fig. 3 is a detail cross-sectional view through the annulus supporting the carrier-frame. Figs. 4 and 5 are side views in detail of the carrier-belt frames, showing my improved device for opening or unfolding and folding the sections thereof. Fig. 6 is a detail sectional end view of the devices shown in Fig. 11, looking in the direction shown by the arrow on said figure. Figs. 7, 8, 9, and 10 are detail views. Fig. 11 is a detail plan view, enlarged, of the tripping or quick-throw mechanism of the pivoted frame. Fig. 12 is a detail view of the levers X and Y and connections.

This invention is an improvement in straw stacker-s and carriers such as are shown and described in my Letters Patent No. 385,634:, dated July 3, 1888; and the object of the present invention is to improve the devices for imparting a lateral vibration to the carrier-belt frames automatically; and the invention consists in the novel construction and arrangement of parts hereinafter described and claimed.

Referring to the accompanying drawings by letter, A designates a frame, which may be mounted 011 a wagon-body or provided with wheels (not shown) for transportation. Upon this frame is supported an annulus V, hereinafterdescribed, and upon said annulus is supported a frame Z, constructed substantially as shown and described in my aforesaid patent, or in other suitable manner.

Serial No. 320,010. (No model.)

Upon frame Z are supported two belt-carrying frame-sections Z Z, the latter being hinged at one end to the former and the former being supported on frame Z by four liinged bars Z at the corners thereof, as described in my said patent. Section Z is adapted to be folded on section Z during transportation, and to facilitate the folding and unfolding thereof I attach arms Z Z to the side bars of section Z at the hinged end thereof. \Vhen unfolded, the arms lie alongside of section Z as shown in Fig. 4, and when folded they extend, as shown in Fig. 5. To fold section Z these arms or handles Z are pulled down, thus raising the outer end of section Z and turning it toward Z unti-lit passes the center of gravity and falls upon frame Z and to unfold the handles are depressed until the section Z again passes the center of gravity, moving in an opposite direction, and falls outward. The extreme end of section Z is usually up in the air, and it is, as ordinarily mounted. extremely difficult to fold and unfold; but these handles enable the operator to quickly and simply manipulate the sections.

B designates a horizontal shaft journaled transversely of frame A, at one end thereof, in suitable bearings in or attached to the side bars A A, and a is a pulley on the outer end of said shaft, by which motion can be transmitted thereto from a suitable engine by belting. (Not shown.)

V designates an annulus or ring, preferably of metal and of large diameter, being about equal in diameter to the width of the frame, and said annulus is supported directly over shaft B upon rollers b I), attached to frame A.

V is an annular depending flange on the inner periphery of annulus V, against which abut studs or lu s V secured at re ular intervals on frame A in such position that the annulus is centered and retained thereon. These lugs preferably have rollers V in their ends to reduce friction between them and flange V. I

V designates a bar supported upon and diametrically of annulus V, and V is a short vertical shaft attached centrally to said bar and having a bevel-gear on its lower end meshing with a bevel-gear G on shaft B, and

also having a gear F on its upper end meshing with a gear G on a short shaft g, journaled in the frame Z, and having asprocketwheel H, by which and suitable belts motion can be transmitted to the carrier-belts. The perimeter of annulus V is provided with sprocket-teeth v, as shown, and it has a series of erforations v 'v for the en "a ement of adj ustable pins (Hereinafter referred to.)

tdesignates a vertical shaft journaled in proper hearings in cross-pieces .M-A of frame A, at the end thereof, opposite shaft B, and S is a large worm-gear loosely mounted on said shaft and having a stud S on its upper face, which is engaged by a horizontal arm or pin S on shaft t.

T is a sprocket-wheel loosely mounted on the upper end of shaft 2, having a stud or pin T, adapted to be engaged by a pin 1" on shaft 73, as indicated, to rotate the wheel with the shaft. Preferably both wheel T and gear S have two or more holes in their webs, and instead of casting studs thereon I employ adjustable pins, as shown, by which the amount of movement of shaft t independently of the gear or pinion can be regulated.

P designates a rectangular frame lying parallel with gear S and transversely of frame A, being pivoted at one end, as at P, to frame A, its opposite or free end being permitted to oscillate or vibrate.

r and q are two shafts journaled longitudinally of frame P in suitable bearings, and on opposite sides of and in the same plane as gear S.

R and Q are worm-gears on said shafts, either of which can be brought into engagement with gear S by swinging the free end of the frame P laterally,

'm and n are sprocket-wheels on said shafts, and K is a sprocket-chain running over both said gears and transmitting motion thereto from a sprocket-wheel D on shaft 13, as indicated in the drawings. The sprockets m and n are at the pivoted end of the frame, so that lateral movement thereof will not disengage chain K therefrom. The free end of frame P is supported on frame A, so that it can move laterally, and it has two proj ecting arms P P, one of which is engaged by a spring-catch L, secured to cross-piece A of the frame A, by which frame P, after shifting, is held until forcibly shifted again.

Y designates a lever pivoted at one end on a cross-piece A of frame A above frame P, and extending outwardly over and between arms P, on which are mounted a pair of lugs Y Y, rising from a strap or bar Y, against which lugs leverY is alternately thrown. The outer end' of said lever Y is pivotally connected to one end of a rod X, the inner end of which is supported in a U-shaped' bracket X, pivotally secured on cross-piece A and to said rod is attached a coiled spring X which bears against a pin y" on rod X and against one end of the'bracket and pulls said rod inward.

Owing to the different pivotal points of attachment of lever Y and bracket X to the .bar A when the lever. Yis pulled forward or backward until the point of attachment of lever Y and rod X is in line with the pivotal points of attachment of said lever and rod to bar A spring X will be tensioned.

XV designates a sliding bar lying longitudinally in frame A and below annulus V, and having an upstandingluglVZwhich is adapted to be engaged by depending pins jj of said annulus. The front end of the bar is loosely connected by a slotted plate W and a pin to lever Y. A sprocket-chain u transmits motion from wheel T to annulus V.

The operation is as follows: The are of movement of thecarrier-frameZ is determined and regulated by the piusjj, which are set closer to or farther from each other, as a long or short vibration of the frame is desired. Motion being imparted to shaft B and the frame P shifted to engage worm Q with gear S, annulus V will turn in one direction until pin j strikes V Bar \V will then be drawn forward, pulling lever Y toward the annulus until it passes a line coincident with the pivots of bracket X and lever Y, when the spring X ,'which has been tensioned by such movement, will pull Y quickly and violently over, making it strike -against the opposite lug Y and shift frame P laterally, causing it to disengage worm Q from gear S and to engage worm .R therewith. This will stop the motion of annulus V and frame Z and the motion of gear S will be reversed. Pin S will leave S, and shaft 25 will remain at a standstill until S has revolved sufficiently to engage another stud S on the opposite side of the single stud, when a reverse movement is impart-ed to shaft t. Sprocket T still remains idle until the shaft 25 has brought pin T into engagement with the stud on said sprocket, when said sprocket is turned and a reverse movement imparted to annulus V and frame Z. The annulus will continue to revolve until pin j strikes 7 andthrows lever Y, and hence frame'P, back to its first position, when (after the parts have remained stationary for a few moments during the reversing of the shaft and gears) movementis imparted to annulus V in the opposite direction. Motion is imparted from sprocket H by a chain H to a shaft H carrying sprockets H which transmit motion by chains H, to the carrier-belt wheels H of the carrier-belts II on frames Z 'Z.

By properly proportioningthat is, enlarging-gear S a suflicient pause might be obtained at the end of each lateral vibration of frame P; but by employing the pins or lugs and loosely mounting sprocket T, as described, the intervals between the movements of the annulus are increased without enlarging the parts to an awkward degree. By using several holes in the sprocket and gear and adjustable pins the interval can be varied, or by projecting pins S and T through shaft 'fthe intervals will be shortened, as the shaft and gear will only have one-half revolution before engaging.

Having thus described my invention, I claim- 1. The combination of the main frame, the revolving annulus mounted thereon and supporting the carrier-belts and their framesnvith the vertical shaft, a Worm-gear, a laterallymovable frame embracing said gear and having two wornrshafts on its opposite sides, the devices for transmitting motion from said shaft to the annulus, and the spring-operated lever-reciprocating bar, and connections, substantially as described,for automatically shiftin g said movable f ram e, substantially as specified.

2. The combination, with the revoluble annulus and the carrier-belt frames supported thereon, and the adjustable pins on said annulus, of .the vertical shaft carrying a loose worm-gear and sprocket-wheel, and a laterally-movable pivoted frame having two wormshafts adapted to respectively engage said worm gear when the frame is shifted, the spring-controlled lever pivoted on the main frame and engaging studs on said movable frame, the movable bar engaging said lever and actuated by the pins of the annulus, and the sprocket-wheels and chains, constructed and arranged substantially as specified.

3. The combination of the shaft 15, the gear S thereon, having pins S and the pin S on said shaft, and the laterally-movable frame P and worms Q and R thereon,with the annulus V, supporting the carrier-belt frames and the devices for driving the annulus from said shaft, and the means, substantially as de scribed, for automatically shifting said frame from the annulus, all substantially as and for the purpose described.

4. The combination of the vertical shaft 2, gear S, and the connections between said shaft and the revoluble support of the carrier-belt frames, with the lever Y, mounted on the main frame and engaging stop-lugs on said m ovable frame, the spring-controlled rod X, attached to said lever, and the longitudinally-movable bar WV, all substantially as and for the purpose described.

5. The combination of the annulus V, having pins j j and supporting the carrier-belt frames, with the vertical shaft t, the sprocket and worm Wheels loosely mounted thereon, the movable frame P, the worms Q and R, supported thereon, the sprockets and chains for driving said worms, the locking-latch L, and devices, substantially as described, for automatically shifting said frame from the annulus, all substantially as and for the purpose described.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.

AUGUST LAMMEDEE.
